Well, partly thin bc she smokes so much, which is sad. I wish young Hollywood didn't consider smoking so "vogue".

She is tiny though. She has absolutely no muscular build, and she may look a little better if she did. (Nothing bulky) More like Ashley Greene, toned and feminine. Recall how her legs appeared in the dress she wore at the MTV movie awards....not good.

Anyway, I think that even if she were not an actor, she'd still be a tiny little thing. She's very petite.

it seems as though she has been filling out a bit lately, she's not as thin as she was when filming Twilight. Makes me feel better about myself, because I'm almost exactly the same age as her, and I've gained a little weight in the last year also. Either way, she's very naturally beautiful, I envy the way she can walk around so casual and look so confident!

Maybe she is just developing her woman's body. I admit, I am not a KStew fan, but am apalled when ppl say she is fat. NO WAY! Not a great actor, I agree with, but really, fat? What does she weigh...100lbs?

anybody else notice the trend here... everyday kristen goes out where what looks suspiciously like a man's shirt. like she just rolled out of bed **ahem** and threw it on and tied it up in a knot. i'm just saying.
